American Wire Gauge (AWG) to MM² Conversion Guide
This post is dedicated to an acknowledgement that due to a modern world of information technology and supply chain, circumstances dictate the need to convert wire sizes into a format understandable to a broader global community of mechanical and electrical engineers, specifically for products not purchased from Arc Components Limited, usually that require additional fittings and components that adhere to the UK and metric standards.
While the necessary wiring and cable load values must always be sought for the job in hand, whether for trade, project or DIY applications, there is a need, in the name of service, to assist engineers presented with "Country Specific" product information.
Please note: The guide presents AWG in its equivalent Imperial and metric sizes and the corresponding AWG load current (Amperage). The table does not offer a metric wire size alternative and does not consider metric cable outer construct (standard and thin wall PVC) measurements.
